I like to use a moderate chili powder, I'm looking for flavor. Can always up the heat with what we called a Christmas pepper in North Texas. Pretty little ornamental plant with many small peppers that change color, green - purple -red. Hotter 'n hell. Thinking NuMex Twilight or Centennial 30,000 to 50,000 Scoville. I expect the whole NuMex line is just as hot. Centennial, Twilight, and another from them all cross pollinate.
